262 MINNESOTA BOTANICAL STUDIES. 



145. Cladonia symphycarpa Fr. var. epiphylla (Ach.) Nyl. 

 In crevices in rocks, rare. Habitat unusual but thallus too large 



for C. ccBsfiticia (Pers.) Fl. Gunflint, July i, 1897, no. 363. 

 Not previously reported from Minnesota. 



146. Cladonia mitrula Tuck. 



On earth, rare. Beaver Bay, July 15, 1897, no. 694. 



147. Cladonia cariosa (Ach.) Spreng. 



On earth, probably frequent. Grand Portage island, June 

 23, 1897, nos. 120 and 146. Gunflint, July i, 1897, no. 324. 

 Misquah hills, July 5, 1897, nos. 509 and 533. Tofte (Carl- 

 ton peak), July 10, 1897, no. 606. Beaver Bay, July 14, 1897, 

 nos. 737 and 739. 



The forms listed here seem to me to be partly intermediate 

 between this and the last having the habit of this, but some are 

 rather small with the squamules usually small. C. mih'ida Tuck, 

 is the common form in southern Minnesota, but the better de- 

 velopment of this region runs into the present species. Of the 

 specimens here listed no. 146 is the best representative of the 

 species and no. 120 the poorest. Some of the smaller ap- 

 proaches C. symphycarpa Fr., which is itself a doubtful species. 



148. Cladonia decorticata Floerk. 



On earth, rare. Beaver Bay, July 14, 1897, no. 738. Not 

 previously reported from Minnesota and new to west of New 

 England.

 1897, nos. 567 and 568. Beaver Bay, July 14, 1897, no. 735.
